General Power Tool Safety Warnings

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings

and instructions may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-

operated (cordless) power tool.

1) WORK AREA SAFETY

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b) Do not operate power tools in explosive atmospheres, such as in the presence of

flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or

fumes.

c) Keep children and bystanders away while operating a power tool. Distractions can

cause you to lose control.

2) ELECTRICAL SAFETY

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not

use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and

matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,

ranges and refrigerators. There is an increased risk of electric shock if your body is earthed

or grounded.

c) Do not expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the

power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged

or entangled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use an extension cord suitable for outdoor

use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

f) If operating a power tool in a damp location is unavoidable, use a ground fault

circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric

shock.

3) PERSONAL SAFETY

a) Stay alert, watch what you are doing and use common sense when operating a

power tool. Do not use a power tool while you are tired or under the influence of

drugs, alcohol or medication. A moment of inattention while operating power tools may

result in serious personal injury.

b) Use personal protective equipment. Always wear eye protection. Protective

equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used

for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch is in the off position before

connecting to power source and/or battery pack, picking up or carrying the tool.

Carrying power tools with your finger on the switch or energizing power tools that have the

switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. A wrench or

a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This enables better

control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and

gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in

moving parts.

g) If devices are provided for the connection of dust extraction and collection facilities,

ensure these are connected and properly used. Use of dust collection can reduce dust-

related hazards.

4) POWER TOOL USE AND CARE

a) The Do not force the power tool. Use the correct power tool for your application.

correct power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not turn it on and off. Any power tool

that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the battery pack from the power

tool before making any adjustments, changing accessories, or storing power tools.

Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children and do not allow persons

unfamiliar with the power tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage

of parts and any other condition that may affect the power tool’s operation. If

damaged, have the power tool repaired before use. Many accidents are caused by

poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting

edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits, etc. in accordance with these

instructions, taking into account the working conditions and the work to be

performed. Use of the power tool for operations different from those intended could result

in a hazardous situation.

5) SERVICE

a) Have your power tool serviced by a qualified repair person using only identical

replacement parts. This will ensure that the safety of the power tool is maintained.

SAFETY INSTRUCTIONS FOR ALL OPERATIONS

Safety Warnings Common for Grinding, Sanding, Polishing,

Carving or Abrasive Cutting-Off Operations

a) This power tool is intended to function as a grinder, sander, polisher, carving or

cut-off tool. Read all safety warnings, instructions, illustrations and specifications

provided with this power tool. Failure to follow all instructions listed below may result in

electric shock, fire and/or serious injury.

b) Operations such as wire brushing are not recommended to be performed with this

power tool. Operations for which the power tool was not designed may create a hazard and

cause personal injury.

c) Do not use accessories which are not specifically designed and recommended by

the tool manufacturer. Just because the accessory can be attached to your power tool, it

does not assure safe operation.

d) The rated speed of the accessories must be at least equal to the maximum speed

marked on the power tool. Accessories running faster than their rated speed can break

and fly apart.

e) The outside diameter and the thickness of your accessory must be within the

capacity rating of your power tool. Incorrectly sized accessories cannot be adequately

guarded or controlled.

f) The arbor size of wheels, sanding drums or any other accessory must properly fit

the spindle or collet of the power tool. Accessories that do not match the mounting

hardware of the power tool will run out of balance, vibrate excessively and may cause loss

of control.

g) Mandrel mounted wheels, sanding drums, cutters or other accessories must be

fully inserted into the collet or chuck. If the mandrel is insufficiently held and/or the

overhang of the wheel is too long, the mounted wheel may become loose and be ejected at

high velocity.

h) Do not use a damaged accessory. Before each use, inspect the accessory such as

abrasive wheels for chips and cracks, sanding drum for cracks, tear or excess wear,

wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect

for damage or install an undamaged accessory. After inspecting and installing an

accessory, position yourself and bystanders away from the plane of the rotating

accessory and run the power tool at maximum no-load speed for one minute.

Damaged accessories will normally break apart during this test time.

i) Wear personal protective equipment. Depending on application, use face shield,

safety goggles or safety glasses. As appropriate, wear dust mask, hearing

protectors, gloves and workshop apron capable of stopping small abrasive or

workpiece fragments. The eye protection must be capable of stopping flying debris

generated by various operations. The dust mask or respirator must be capable of filtrating

particles generated by your operation. Prolonged exposure to high intensity noise may cause

hearing loss.

j) Keep bystanders a safe distance away from work area. Anyone entering the work

area must wear personal protective equipment. Fragments of workpiece or of a broken

accessory may fly away and cause injury beyond immediate area of operation.

k) Hold power tool by insulated gripping surfaces only, when performing an operation

where the cutting accessory may contact hidden wiring or its own cord. Cutting

accessory contacting a “live” wire may make exposed metal parts of the power tool “live”

and could give the operator an electric shock.

l) Always hold the tool firmly in your hand(s) during the start-up. The reaction torque of

the motor, as it accelerates to full speed, can cause the tool to twist.

m) Use clamps to support workpiece whenever practical. Never hold a small workpiece

in one hand and the tool in the other hand while in use. Clamping a small workpiece

allows you to use your hand(s) to control the tool. Round material such as dowel rods, pipes

or tubing have a tendency to roll while being cut, and may cause the bit to bind or jump

toward you.

n) Position the cord clear of the spinning accessory. If you lose control, the cord may be

cut or snagged and your hand or arm may be pulled into the spinning accessory.

o) Never lay the power tool down until the accessory has come to a complete stop.

The spinning accessory may grab the surface and pull the power tool out of your control.

p) After changing the bits or making any adjustments, make sure the collet nut, chuck

or any other adjustment devices are securely tightened. Loose adjustment devices

can unexpectedly shift, causing loss of control, loose rotating components will be violently

thrown.

q) Do not run the power tool while carrying it at your side. Accidental contact with the

spinning accessory could snag your clothing, pulling the accessory into your body.

r) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the

housing and excessive accumulation of powdered metal may cause electrical hazards.

s) Do not operate the power tool near flammable materials. Sparks could ignite these

materials.

t) Do not use accessories that require liquid coolants. Using water or other liquid coolants

may result in electrocution or shock.

FURTHER SAFETY INSTRUCTIONS FOR ALL OPERATIONS

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged rotating wheel, sanding pad, brush

or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory

which in turn causes the uncontrolled power tool to be forced in the direction opposite of the

accessory’s rotation.

For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel

that is entering into the pinch point can dig into the surface of the material causing the wheel to

climb out or kick out. The wheel may either jump toward or away from the operator, depending

on direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break

under these conditions.

Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and

can be avoided by taking proper precautions as given below:

a) Maintain a firm grip on the power tool and position your body and arm to allow you

to resist kickback forces. The operator can control kickback forces, if proper precautions

are taken.

b) Use special care when working corners, sharp edges etc. Avoid bouncing and

snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the

rotating accessory and cause loss of control or kickback.

c) Do not attach a toothed saw blade. Such blades create frequent kickback and loss of

control.

d) Always feed the bit into the material in the same direction as the cutting edge is

exiting from the material (which is the same direction as the chips are thrown).

Feeding the tool in the wrong direction causes the cutting edge of the bit to climb out of the

work and pull the tool in the direction of this feed.

e) When using rotary files, cut-off wheels, high-speed cutters or tungsten carbide

cutters, always have the work securely clamped. These wheels will grab if they become

slightly canted in the groove, and can kickback. When a cut-off wheel grabs, the wheel itself

usually breaks. When a rotary file, high-speed cutter or tungsten carbide cutter grabs, it may

jump from the groove and you could lose control of the tool.

Safety Warnings Speciﬁ c for Grinding and Abrasive

Cutting-Off Operations

a) Use only wheel types that are recommended for your power tool and only for

recommended applications. For example: do not grind with the side of a cut-off

wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to

these wheels may cause them to shatter.

b) For threaded abrasive cones and plugs use only undamaged wheel mandrels with

an unrelieved shoulder flange that are of correct size and length. Proper mandrels

will reduce the possibility of breakage.

c) Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to

make an excessive depth of cut. Overstressing the wheel increases the loading and

susceptibility to twisting or snagging of the wheel in the cut and the possibility of kickback or

wheel breakage.

d) Do not position your hand in line with and behind the rotating wheel. When the

wheel, at the point of operation, is moving away from your hand, the possible kickback may

propel the spinning wheel and the power tool directly at you.

e) When wheel is pinched, snagged or when interrupting a cut for any reason, switch

off the power tool and hold the power tool motionless until the wheel comes to a

complete stop. Never attempt to remove the cut-off wheel from the cut while the

wheel is in motion, otherwise kickback may occur. Investigate and take corrective

action to eliminate the cause of wheel binding.

f) Do not restart the cutting operation in the workpiece. Let the wheel reach full

speed and carefully reenter the cut. The wheel may bind, walk up or kickback if the

power tool is restarted in the workpiece.

g) Support panels or any oversized workpiece to minimize the risk of wheel pinching

and kickback. Large workpieces tend to sag under their own weight. Supports must be

placed under the workpiece near the line of cut and near the edge of the workpiece on both

sides of the wheel.

h) Use extra caution when making a “pocket cut” into existing walls or other blind

areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can

cause kickback.

Additional Safety Information

• Do not use Type 11 (flaring cup) wheels on this tool. Using inappropriate accessories can

result in injury.

• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long

hair can be caught in moving parts.

• An extension cord must have adequate wire size (AWG or American Wire Gauge) for

safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is

16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage

resulting in loss of power and overheating. When using more than one extension to make up

the total length, be sure each individual extension contains at least the minimum wire size. The

following table shows the correct size to use depending on cord length and nameplate ampere

rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the

cord.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use

face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other

construction activities contains chemicals known to the State of California to cause cancer, birth

defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce

your exposure to these chemicals: work in a well ventilated area, and work with approved safety

equipment, such as those dust masks that are specially designed to filter out microscopic particles.

• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and

other construction activities. Wear protective clothing and wash exposed areas with

soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote

absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disperse dust, which may cause serious and

permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection

appropriate for the dust exposure. Direct particles away from face and body.

WARNING: Always wear proper personal hearing protection that conforms to ANSI

S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product

may contribute to hearing loss.

WARNING: Always use eye protection. All users and bystanders must wear eye protection

that conforms to ANSI Z87.1.

WARNING: When not in use, place grinder on a stable surface where it will not move

inadvertantly, roll or cause a tripping or falling hazard. Serious personal injury may result.

CAUTION: To reduce the risk of personal injury, use extra care when working into a corner or

edge because a sudden, sharp movement of the tool may be experienced when the wheel or other

accessory contacts a secondary surface or a surface edge.

Precautions To Take When Sanding Paint

1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the

contaminated dust. The greatest danger of lead poisoning is to children and pregnant women.

2. Since it is difficult to identify whether or not a paint contains lead without a chemical analysis,

we recommend the following precautions when sanding any paint:

PERSONAL SAFETY

1. No children or pregnant women should enter the work area where the paint sanding is being

done until all clean up is completed.

2. A dust mask or respirator should be worn by all persons entering the work area. The filter

should be replaced daily or whenever the wearer has difficulty breathing.

NOTE: Only those dust masks suitable for working with lead paint dust and fumes should be

used. Ordinary painting masks do not offer this protection. See your local hardware dealer for

the proper NIOSH-approved mask.

3. NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingesting

contaminated paint particles. Workers should wash and clean up BEFORE eating, drinking or

smoking. Articles of food, drink, or smoking should not be left in the work area where dust

would settle on them.

ENVIRONMENTAL SAFETY

1. Paint should be removed in such a manner as to minimize the amount of dust generated.

2. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils

thickness.

3. Sanding should be done in a manner to reduce tracking of paint dust outside the work area.

CLEANING AND DISPOSAL

1. All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the duration

of the sanding project. Vacuum filter bags should be changed frequently.

2. Plastic drop cloths should be gathered up and disposed of along with any dust chips or other

removal debris. They should be placed in sealed refuse receptacles and disposed of through

regular trash pick-up procedures.

During clean up, children and pregnant women should be kept away from the immediate work

area.

3. All toys, washable furniture and utensils used by children should be washed thoroughly before

being used again.

MAINTENANCE

WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool

from power source before making any adjustments or removing/installing attachments

or accessories. Before reconnecting the tool, depress and release the trigger switch to

ensure that the tool is off.

Cleaning

WARNING: Blowing dust and grit out of motor and switch actuator using clean, dry compressed

air is a necessary regular maintenance procedure. Dust and grit containing metal particles often

accumulate on interior surfaces and could create an electrical shock or electrocution if not

frequently cleaned out. It is recommended that a ground fault circuit interrupter (GFCI) is utilized to

further protect the user from electric shock resulting from the accumulation of conductive particles.

If the tool is deactivated by the GFCI, unplug the tool and check and clean the tool before resetting

the GFCI. ALWAYS WEAR SAFETY GLASSES (ANSI Z87.1) when cleaning or using this tool.

WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts

of the tool. These chemicals m ay weaken the plastic materials used in these parts. Use a cloth

dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse

any part of the tool into a liquid.

Lubrication

Your power tool requires no additional lubrication.

1) SÉCURITÉ DU LIEU DE TRAVAIL

a) Tenir l’aire de travail propre et bien éclairée. Les lieux encombrés ou sombres sont

propices aux accidents.

b) Ne pas faire fonctionner d’outils électriques dans un milieu déflagrant, tel qu’en

présence de liquides, de gaz ou de poussières inflammables. Les outils électriques

produisent des étincelles qui pourraient enflammer la poussière ou les vapeurs.

c) Éloigner les enfants et les personnes à proximité pendant l’utilisation d’un outil

électrique. Une distraction pourrait en faire perdre la maîtrise à l’utilisateur.

2) SÉCURITÉ EN MATIÈRE D’ÉLECTRICITÉ

a) Les fiches des outils électriques doivent correspondre à la prise. Ne jamais modifier

la fiche d’aucune façon. Ne jamais utiliser de fiche d’adaptation avec un outil

électrique mis à la terre. Le risque de choc électrique sera réduit par l’utilisation de fiches

non modifiées correspondant à la prise.

b) Éviter tout contact physique avec des surfaces mises à la terre comme des tuyaux,

des radiateurs, des cuisinières et des réfrigérateurs. Le risque de choc électrique est

plus élevé si votre corps est mis à la terre.

c) Ne pas exposer les outils électriques à la pluie ou à l’humidité. La pénétration de l’eau

dans un outil électrique augmente le risque de choc électrique.

d) Ne pas utiliser le cordon de façon abusive. Ne jamais utiliser le cordon pour

transporter, tirer ou débrancher un outil électrique. Tenir le cordon éloigné de

la chaleur, de l’huile, des bords tranchants et des pièces mobiles. Les cordons

endommagés ou enchevêtrés augmentent les risques de choc électrique.

e) Pour l’utilisation d’un outil électrique à l’extérieur, se servir d’une rallonge

convenant à cette application. L’utilisation d’une rallonge conçue pour l’extérieur réduira

les risques de choc électrique.

f) S’il est impossible d’éviter l’utilisation d’un outil électrique dans un endroit

humide, brancher l’outil dans une prise ou sur un circuit d’alimentation dotés d’un

disjoncteur de fuite à la terre (GFCI). L’utilisation de ce type de disjoncteur réduit les

risques de choc électrique.

3) SÉCURITÉ PERSONNELLE

a) Être vigilant, surveiller le travail effectué et faire preuve de jugement lorsqu’un outil

électrique est utilisé. Ne pas utiliser d’outil électrique en cas de fatigue ou sous

l’influence de drogues, d’alcool ou de médicaments. Un simple moment d’inattention

en utilisant un outil électrique peut entraîner des blessures corporelles graves.

b) Utiliser des équipements de protection individuelle. Toujours porter une protection

oculaire. L’utilisation d’équipements de protection comme un masque antipoussière, des

chaussures antidérapantes, un casque de sécurité ou des protecteurs auditifs lorsque la

situation le requiert réduira les risques de blessures corporelles.

c) Empêcher les démarrages intempestifs. S’assurer que l’interrupteur se trouve à la

position d’arrêt avant de relier l’outil à une source d’alimentation et/ou d’insérer un

bloc-piles, de ramasser ou de transporter l’outil. Transporter un outil électrique alors

que le doigt repose sur l’interrupteur ou brancher un outil électrique dont l’interrupteur est à

la position de marche risque de provoquer un accident.

d) Retirer toute clé de réglage ou clé avant de démarrer l’outil. Une clé ou une clé de

réglage attachée à une partie pivotante de l’outil électrique peut provoquer des blessures

corporelles.

e) Ne pas trop tendre les bras. Conserver son équilibre en tout temps. Cela permet de

mieux maîtriser l’outil électrique dans les situations imprévues.

f) S’habiller de manière appropriée. Ne pas porter de vêtements amples ni de bijoux.

Garder les cheveux, les vêtements et les gants à l’écart des pièces mobiles. Les

vêtements amples, les bijoux ou les cheveux longs risquent de rester coincés dans les pièces

mobiles.

g) Si des composants sont fournis pour le raccordement de dispositifs de dépoussiérage

et de ramassage, s’assurer que ceux-ci sont bien raccordés et utilisés. L’utilisation

d’un dispositif de dépoussiérage peut réduire les dangers engendrés par les poussières.

4) UTILISATION ET ENTRETIEN D’UN OUTIL ÉLECTRIQUE

a) Ne pas forcer un outil électrique. Utiliser l’outil électrique approprié à l’application.

L’outil électrique approprié effectuera un meilleur travail, de façon plus sûre et à la vitesse

pour laquelle il a été conçu.

b) Ne pas utiliser un outil électrique dont l’interrupteur est défectueux. Tout outil

électrique dont l’interrupteur est défectueux est dangereux et doit être réparé.

c) Débrancher la fiche de la source d’alimentation et/ou du bloc-piles de l’outil

électrique avant de faire tout réglage ou changement d’accessoire ou avant de

ranger l’outil. Ces mesures préventives réduisent les risques de démarrage accidentel de

l’outil électrique.

d) Ranger les outils électriques hors de la portée des enfants et ne permettre à

aucune personne n’étant pas familière avec un outil électrique ou son mode

d’emploi d’utiliser cet outil. Les outils électriques deviennent dangereux entre les mains

d’utilisateurs inexpérimentés.

e) Entretien des outils électriques. Vérifier si les pièces mobiles sont mal alignées ou

coincées, si des pièces sont brisées ou présentent toute autre condition susceptible

de nuire au bon fonctionnement de l’outil électrique. En cas de dommage, faire

réparer l’outil électrique avant toute nouvelle utilisation. Beaucoup d’accidents sont

causés par des outils électriques mal entretenus.

f) S’assurer que les outils de coupe sont aiguisés et propres. Les outils de coupe bien

entretenus et affûtés sont moins susceptibles de se coincer et sont plus faciles à maîtriser.

g) Utiliser l’outil électrique, les accessoires, les forets, etc. conformément aux

présentes directives en tenant compte des conditions de travail et du travail à

effectuer. L’utilisation d’un outil électrique pour toute opération autre que celle pour laquelle

il a été conçu est dangereuse.

5) RÉPARATION

a) Faire réparer l’outil électrique par un réparateur professionnel en n’utilisant que

des pièces de rechange identiques. Cela permettra de maintenir une utilisation sécuritaire

de l’outil électrique.

CONSIGNES DE SÉCURITÉ POUR TOUTES LES OPÉRATIONS

Consignes communes de sécurité propres au meulage,

ponçage, polissage, à la gravure ou au tronçonnage abrasif

a) Cet outil électrique a été conçu pour être utilisé comme outil à meuler, poncer,

polir, graver ou tronçonner. Lire toutes les consignes de sécurité, les directives, les

illustrations et les caractéristiques techniques fournies avec cet outil électrique.

Tout manquement aux directives suivantes pose des risques de chocs électriques, d’incendie

et/ou de blessures graves.

b) Les opérations de brossage métallique ne sont pas recommandées avec cet outil

électrique. Toute utilisation de cet outil électrique dans un but autre que celui pour lequel il

a été conçu est dangereuse et pose des risques de dommages corporels.

c) Ne pas utiliser des accessoires qui n’ont pas été spécialement conçus pour cet outil

ou recommandés par son fabricant. Le fait qu’un accessoire peut être connecté à l’outil

ne veut pas automatiquement dire que son utilisation ne posera aucun risque.

d) La vitesse nominale des accessoires utilisés doit être au moins équivalente à la

vitesse maximale apposée sur l’outil. Les accessoires utilisés à une vitesse supérieure à

leur vitesse nominale peuvent éclater ou se détacher de l’outil.

e) Le diamètre externe et l’épaisseur de l’accessoire utilisé doivent se conformer aux

spécifications de la plaque signalétique de l’outil électrique. Les accessoires aux

spécifications incorrectes ne peuvent être ni maintenus ni contrôlés de façon adéquate.

f) L’alésage des meules, tambours de ponçage, ou de tout autre accessoire, doit

correspondre parfaitement à la taille de la broche ou de la douille de l’outil

électrique. Les accessoires ne correspondant pas au dispositif d’installation de l’outil

électrique ne tourneront pas correctement, vibreront de façon excessive et pourront causer

la perte de contrôle de l’outil.

g) Les meules montées sur mandrin, tambours de ponçage, fraises ou autres

accessoires doivent être pleinement insérés sur la douille ou le mandrin. Si le

mandrin est insuffisamment maintenu et/ou que le porte-à-faux de la meule est trop

important, la meule installée pourra se dégager et être éjectée à grande vitesse.

h) Ne pas utiliser d’accessoire endommagé. Avant toute utilisation, vérifier que

les accessoires, comme les meules abrasives et les tambours de ponçage, ne

comportent aucune fissure ou cassure, ou ne sont affectés d’aucune usure

excessive, et que les fils des brosses métalliques ne sont ni lâches ni endommagés.

En cas de chute, vérifier que l’outil électrique ou l’accessoire n’a pas été

endommagé, et remplacer toute pièce abîmée. Après avoir inspecté et installé

un accessoire, se positionner, soi-même et tout individu présent, hors du plan

de rotation de l’accessoire et laisser tourner l’outil une minute à sa vitesse à vide

maximale. En général, les accessoires endommagés se brisent pendant le temps d’essai.

i) Porter un équipement de protection individuelle. Utiliser un masque facial, des

lunettes de sécurité ou des lunettes protectrices en fonction de l’application. Au

besoin, porter un masque antipoussières, des protecteurs auditifs, des gants et

un tablier d’atelier capable d’arrêter de petits fragments d’abrasifs ou de pièces.

La protection oculaire doit être en mesure d’arrêter tout débris produit par les diverses

opérations et le masque antipoussières ou le respirateur, de filtrer les particules produites par

l’opération en cours. Une exposition prolongée à un bruit d’intensité élevée pourrait causer

une perte auditive.

j) Éloigner tout observateur à une distance sécuritaire de la zone de travail. Toute

personne qui pénètre dans la zone de travail devra également porter un équipement

de protection individuelle. Il est possible qu’un fragment de pièce ou un accessoire brisé

soit projeté et provoque des blessures au-delà de la zone immédiate de travail.

k) Tenir l’outil électrique uniquement par sa surface de prise isolée dans une situation

où l’accessoire de coupe pourrait entrer en contact avec un câble électrique

dissimulé ou avec son propre cordon d’alimentation. Tout contact entre un fil «sous

tension » et l’accessoire de coupe pourrait également mettre « sous tension» les pièces

métalliques exposées de l’outil et électrocuter l’opérateur.

l) Maintenir systématiquement l’outil fermement dans vos mains au démarrage.

L’effet de couple du moteur, alors qu’il accélère pour tourner à plein régime pourra causer la

torsion de l’outil.

m) Utiliser des colliers de serrage pour soutenir la pièce à travailler chaque fois que

possible. Ne jamais maintenir une petite pièce d’une main, et tenir l’outil en marche

de l’autre. Arrimer une petite pièce permettra d’utiliser vos mains pour contrôler l’outil. Les

matériaux arrondis, comme les goujons, tuyaux ou tubulures ont tendance à rouler pendant

la coupe et faire sauter la fraise vers l’utilisateur ou la bloquer.

n) Positionner le cordon d’alimentation hors d’atteinte de l’accessoire en mouvement.

En cas de perte de maîtrise, il est possible de couper ou d’effilocher le cordon et la main ou

le bras de l’utilisateur risqueraient d’être happés par l’accessoire en mouvement.

o) Ne jamais déposer l’outil électrique avant l’immobilisation complète de l’accessoire.

L’accessoire en mouvement risquerait de mordre dans la surface et de projeter l’outil

électrique.

p) S’assurer que l’écrou de la douille de serrage, le mandrin ou tout autre dispositif de

réglage, est fermement resserré après tout changement d’organe de coupe ou de

réglage. Les dispositifs de réglage insuffisamment resserrés peuvent bouger inopinément et

faire perdre le contrôle de l’outil, et être violemment éjectés.

q) Mettre l’outil hors tension pour tout déplacement de celui-ci par l’utilisateur. Un

contact accidentel avec l’accessoire en mouvement pourrait happer les vêtements de

l’opérateur et projeter l’accessoire contre son corps.

r) Nettoyer régulièrement les évents de l’outil électrique. Le ventilateur du moteur

aspirera la poussière à l’intérieur du boîtier. Une accumulation excessive de poudre métallique

représente un danger d’origine électrique.

s) Ne pas faire fonctionner l’outil électrique à proximité de matières inflammables. Les

étincelles produites risquent de les enflammer.

t) Ne pas utiliser d’accessoires qui exigent l’utilisation d’un liquide de refroidissement.

L’utilisation d’eau ou de tout autre liquide de refroidissement pourrait se solder par une

électrocution ou une secousse électrique.
